I bought six MultiPurpose contact sensors and I’ve had nothing but problems with these.
They often do not show open or close correctly and I’ve had two completely stop working and stuck in “open.”
One sensor was perminantly stuck in “open.” I tried everything with ST support. Move it closer to hub, moved router away, tried reconnecting, etc. ST sent me new one, connected after 5-10m of trying.
So I had 2 not on a door yet and I was testing them before connecting new sensor. Both worked before trying to connect new sensor. But now one of those doesn’t work after connecting the new one.
Is there a sensor max or something?
I can’t figure what’s going with these things.
